<code><pre>
the field to the right of button 'Eval as row' enter a row number
the long field to the right of that enter a method:
  :ex, format(0..6,"bold","back:blue","italic")
          would format cells 0..6 in the row as bold font,italic font and blue background

when invoked global variable $grid is set to the current TableSheet (Wx::Grid)
so as row 0: e("$grid.auto_size")
would expand all columns to fit thier contents

see eval as row methods for further explanation
